Upgrading converter due to fan noise

[Jammer]

While the topic is controversial, some who question the safety benefit of the LP gas detector disconnect or remove them rather than installing a switch. They typically draw around 100 mA.

The breakaway switch should not draw power unless there is dirt bridging the contacts, in which case the simplest thing might be to just replace it.

Also, phantom draw is possible from the umbilical connector, if it gets dirty and wet, as may happen during storage.
